We would like to announce the following about the two Giant Panda Xiao Xiao and Lei Lei, who were born at Ueno Zoo on June 23, 2021.

Xiao Xiao's latest news

Xiao Xiao's health is good, but since mid-October, we have noticed that the fur on her hind legs has been gradually getting shorter. No abnormalities have been observed on her skin, so we are considering the possibility of chafing or partial shedding, but we will continue to carefully monitor the situation.

We adjust the enclosure location according to the animals' condition and the weather, but since it is a comfortable season for pandas, we generally allow them free movement between indoor and outdoor areas. There are no particular abnormalities in their feeding or behavior, and they are in good condition.

They are fed mainly bamboo such as moso bamboo, shinotake bamboo, and Madake bamboo, with side dishes such as panda dumplings, carrots, and apples given as needed.

Xiao Xiao has been undergoing Eurasian Moorhen training (*) since July 16, 2023. Through repeated training, it will become possible to safely manage the health of pandas by touching them with minimal stress. Training was temporarily suspended when Ri Ri and Shin Shin went into quarantine, but resumed on October 25, 2024, after their return to China. Currently, training is being conducted for X-ray imaging and other preparations for quarantine.
